This invention relates to improvements in corrugating machines.

The object of the invention is the production of a machine for corrugating plain strips or sheets of material, such as paper, with corrugations disposed on a bias or diagonally across the face of the strip or sheet of ma terial operated upon.

The second object of the invention is the production of a machine having drums with corrugations parallel to their axes, and with which plain strips or sheets of material can easily have impressed therein corrugations inclined to the longitudinal axes o the drums.

The organization of the invention co1nprises a pair of rotating shafts, which each slidably support a corrugating drum consisting of a pair of similar portions. Cams are provided for laterally and simultaneously reciprocating the portions of each of the drums during their rotations, and while corrugating a plain strip or sheet of material passing between them in a'direction oblique to longitudinal axes of the drums.

In the acompa-nying drawings Fig. 1 represents an elevation with a partial axial section as on the line 1, 1, of Fig. 2 of an exemplification of the improved corrugating machine. Fig. 2 shows a top view of Fig. 1; Fig. 3 indicates a section of Fig. 1 on the line 3, 3; Fig. 4 is a section of Fig. 1 on the line 4, 4; Fig. 5 represents a top view of the corrugating machine in operative position; Fig. 6 shows a top view of the strip or sheet of material after having been corrugated; Fig. 7 indicates a section of Fig. 6 on the line 7, 7; Fig. 8 indicates a top plan view of one end of one of the portions of the upper drum of the machine; Fig. 9 shows an'elevation partly in vertical axial section of a modification of the corrugating machine, Fig. 10 shows a section of Fig. 9 on the ine 1O, 10; Fig. 11 indicates a section of Fig. 9 on the line 11, 11 and Fig. 12 shows an enlarged partial section of Fig. 9 on the line 12, 12. l

The corrugating machine in this exemplification comprises the end frames desi nated in their entireties by the numerals and 30. The end frame 20 has formed therewith the upper journal bearing 21 and the lower journal bearing 22. The end frame has formed therewith the upper journal bearing 31 and the lower journal bearing 32. A threaded boss 3 extends from the foot of the frame 30.

The upper shaft 40 having the axial opening 41 has its end portions journaled inthe upper journal bearings 21 and 31. The shaft 40 has fastened thereto the similar feathers 42 and the similar collars 43. The lower shaft 46 having the axial opening 47 is journalled in the lower journal bearings 22 and 32. The shaft 46 has fastened thereto the similar feathers 48 and the similar collars 49.

On the shaft 40 is slidably supported the upper drum comprising the portions 50 and 51 having the corrugations 52 lengthwise thereof. The said portions 50 and 51 are slidahly supported on the feathers 42. An arcuate lug 53 having the projecting portion 54 extends from the portion 51 of the upper drum, and the arcuate lug 55 having the projection 56 extends from the portion 50 of the upper drum. A roller 57 is j ournaled on the projecting portion 54 and a roller 58 is j ournaled on the projecting portion 56.

On the shaft 46 is slidably supported the bottom drum comprising the portions 59 and 60 having the corrugations 61 lengthwise thereof. The said portions 59 and 60 slidably engage the feathers 48. An arcuate lug 62 having the projecting portion 63 extends from the portion 60 of the bottom drum and an arcuate lug 64 having the projecting portion 65 extends from the portion 59 of the lower drum. A roller 66 is journaled on the projecting portion 63 and a roller 67 is journaled on the projecting portion 65.

An. internal groove cam 68 extends from and is detachab-ly fastened to the inner face of the frame 20, and is indicated having the internal cam groove 69. The rollers 57 and 58 engage the cam groove 69.

An internal groove cam 72 extends from and is detachably fastened to the innerface of the frame 30 and is indicated having the internal cam groove 73. The rollers 66 and 67 engage the cam groove 73.

The internal groove cams 69 and 7 3 are constructed so that the advance lateral movement of the portions of the drums is longer in time than its return movement. By this means when portions of each drum simult 'neously corrugate the sheet of material as shown in Fig. 3, they move for a short distance in same direction to prevent injury to the st 1p or sheet of material.

To the shaft 10 fastened tne spur and to the shaft &6 is fastened tne spar gear 79, which meshes with the spur gear (0 said spur gears may be omitted as t. i i rugations 52 and 61 mesh with each otlie'-' to maintain the drums in proper operative position. To the shaft 46 is fastened the pulley which is turned by a belt not shown.

In the axial opening of the shaft 20 located a core 31 of electric insulating mat rial around which is wound a w re coil 35, and around the coil is positi -e( a tube 86 of electric insulating mater; the axial opening t? of the shaft is located core 88 of electric insulating mammal similar to 8e, and the wire coil 89 wound around the core 38. A tu e 90 of electric insulating material encloses the coil 89 A stand adjacent to the frame 30 is inl I mates in tirety by the numeral 92. 1 ie comprises the rods or pipes 93 and 9- rod or pipe 93 its lower end is in threa engagement with the boss 33. A cross 9 in threaded engagement with the upper of the rod or pipe 93, and the lower end of rod or pipe 94: is in threaded engagement wita said cross 95.

One end of the core 8a is supported in the Y 96 and fastened in position by the screw 97, and one end of the core 83 is supported in cross and fastened in position by the screw 98.

A stand 100 similar to the stand 92 is located adjacent to the frame 20 and is shown with the rod or pipe 93, the cross 95 with its screw 98, and the Y 96 with its screw 97. A threaded boss 101 engages the lower threaded end of the rod or pipe 93 of the stand 100. The end portion of the core 8 1 adjacent to the frame 20 is supported in the a 96 of the stand 100. and the end portion of the core 88 adj acent to the stand 100 is supported in the cross 98 of the said stand 100. A wire 105 is connected to one of the ends of each of the coils 85 and 89, and a wire 106 is connec ed to the other end of each of said 0- s. The Wires 105 and 106 lead to a source of electric current.

Referring to Fig. 5 the corrugating ma chine is indicated with its upper roller com prising the portions 50 and 51 with their frames 20 and 30 and their other appurtenances. A roller 107 is indicated with its journal brackets 108 and carries a roll of the sheet of material or paper 110, which is to be corrugated and is indicated passing between 1,see,e12

the drums in the direction of the arrow A. to form the corrugations.

To use the machine the coils 85 and 89 are electrically energized to heat the drums having the portions 50, 51 and 59, 60. The said drums are turned in this instance in the direction of the arrows indicated in Fig. 3 by imparting rotation to the pulley 80. The sheet of material or paper 110 to be corrugated is posizioned between the corrugatons 52 and 61 of the drums. During the rotations of the drums the sheet or paper is corrugated, and the heat generated by the coils 85 and 89 heat the same a suiiicient amount to prevent injury thereto while being corrugated and to retain the corrugations in proper form. V hile the drums are turned for one half a revolution the paper is passing bet. een them in the direction of the arrow r ,Fig. 5 and it is also moving laterally in the direction of the arrow B. it the same time the portions 50 and 59 of the drums are moving laterally in the direction of the said arrow B, and the portions 51 and 60 are moving in a direction opposite the arrow B, to be in position for the sheet 110 for the next half revolution of the drums to corrugate it and move with another portion of the sheet of material or paper in the direction of the arrow 13. The portions of the drums move laterally by the coacting of the rollers 54, 58, and 66, ($7 with their respective groove cams.

It will be noted that instead of the heating elements having the cores 8% and 88, a gas heater or a pipe heated with steam may be used.

Referring to Figs. 9 to 12 the modified corrugating machine comprises the end frames designated in their entireties by the numerals and 135.

The end frame 120 is indicated with the vertical member 121, which extends up from the base or foot 122. From the upper end of the vertical member 121 extends the horizontal upper journal bearing 123, having the boss 12 A horizontal lower journal bearing 128 with the boss 129 also extends from the vertical member 121. A boss 130 extends from the base or foot 122. The bosses 12 1, 129 and 130 have their vertical axes in the same line.

The end frame is indicated with the vertical member 136 which extends up from the base or foot 137. From the upper end of the vertical member 136 extends the horizontal upper journal bearing 138, and with the latter is formed the vertical journal bearing 139, which latter extends'laterally from the horizontal journal bearin g 138. 1; horizontal lower ournal bearing 1&3 extends from the vertical member 136, and with the latter is formed the vertical journal bearing 141-, which later extends laterally from the horizontal journal bearing 1 13. A boss 145 extends from the foot 137. An upper hollow shaft 146 having the axial opening 147, has its ends ournaled in the journal bearings 123 and 138. A spur. gear 148is fastened to one end of the shaft'146. A lower hollow shaft 150 having the axial opening 151, has its ends journaled in the journal bearings 128 and 143. A pulley 152 is fastened to one end of the shaft 150. A spur gear 15.3 is fastened to the other end of the shaft 150, and meshes with the spur gear 148. A journal pin 156, extends from and has its lower portion fastened to the boss 124. An upper return roller 157 is journaled on the journal pin 156. A journal pin 158 has its ends supported in the bosses 129 and 130 and has journaled thereon the lower return roller 159. From the boss 145, extends the vertical shaft 162, which extends through the journal bearings 139 and 144. A spur gear 16.3 is j ournaled on the shaft 162 between the journal bearings 139 and 144.

On the shaft 146' is fastened a drum designated in its entirety by the numeral 164, having the dovetail longitudinal notches 165, in which are slidably supported the dovetail longitudinal projections 166 of the teeth 168, which extend. lengthwise of the drum 164.

On the lower shaft 150 is fastened a drum designated in its entirety by the numeral 17 2 similar to 164, having the dovetail longitudinal notches 173, in which are slidably supported the dovetail longitudinal projections 174 of the teeth 175, which extend lengthwise of the drum 17 2. The teeth 168 and 175 mesh with each other.

In each of the axial openings 147 and 151 of the shafts 145 and 150 is supported an electric heating element. Said element comprises the core 178 of electric insulating material, around which is wound the wire coil 179, and around the latter is supported the tube 180 of electric insulating material. From one end of each of the wire coils 179 extends the wire 181, and from the other end of each of said coils extends the wire 182. The wires 181 and 182 lead to a source of electric current not shown.

Adjacent to the spur gears 148 and 153, and the pulley 152 are located supporting stands, which each comprise the rods or pipes 185, 186, the cross 187 having the screw 188, and the Y 190 with the screw 191. The ends of the core 178 in the upper shaft 146 are supported and fastened in the Ys 1.90 and the ends of the core 178 in the lower shaft 150 are supported and fastened in the crosses 187.

To use the modified corrugating machine (Figs. 9 to 12), the coils 179 in the hollow shafts 146 and 150 are electrically energized to heat the drums 164 and 172 and their teeth 168 and 175. The said drums are turned in the direction of the arrows indicated in Figs. 11 and 12, by imparting rotation to the pulley 152. The sheet of material or paper 110 to be corrugated as indicated at 111 is positioned between the teeth 168 and 175. During the rotations of the drums 164, and 17 2, the sheet of material or paper 110 is corrugated, and the heat generated by the coils 179 heats the same a sufiicient amount to prevent injury thereto while being corrugated and to retain the corrugation in proper form.

lVhile the drums are turning and just after the teeth 168 and 175 have been in mesh and the paper is running forwardly in the direction of the arrow A and laterally in the direction of the arrow B the spur gear 163 is moving the teeth of both drums in a direction opposite to the arrow B. At the end of a half of arevolution the teeth of both drums one after the other, are returned to their original lateral position by the pulleys 157 and 159 as indicated at C Fig. 10 to be in position for the sheet 110 for the next half revolution of the drums to corrugate it and move with another portion of the sheet of material or paper in a direction opposite of the arrow B Various modifications may be made in the invention and the present exemplification is to be taken as illustrative and not limitative thereof.
